R: Mapping Super Typhoon Yolanda (Haiyan) Track

After reading Enrico Tonini post, I decided to map the super typhoon Haiyan track using OpenStreetMap, maptools, and ggplot2. If mapping with googleVis was possible with 13 lines only, that can also be achieved with the packages I used; but because I play with the aesthetic of the map, thus I got more than that. The data was taken from Weather Underground, and just to be consistent with the units from JMA Best Track Data, which I utilized for mapping typhoon Labuyo (Utor), the wind speed in miles per hour (mph) was converted to knots. So here is the final output,

Labels:

TD - Tropical Depression

TS - Tropical Storm

TY - Typhoon

STY - Super Typhoon

As for the super typhoon, please don't visit my country again. I would like to thank all who prayed for Philippines, especially for countries who helped us recover from this tragedy.
